The Unholy game is being developed on the Unreal Engine. Players will take on the role of Siada, a mother who is trying to save herself and her missing child. It is noted that to do this, they will have to explore the abandoned city, as well as study its rich history. The developers also note that during the game, the heroine will have to fight her own madness so as not to eventually become crazy. In addition, maniacs with various monsters will also pose a danger, as well as an unknown plague that is gradually capturing the entire city.
